Answer:
<em>Which arrow or arrows represent a release of carbon dioxide? What process is occurring at the arrow(s) you selected?</em>
- From factory emissions to carbon dioxide in atmosphere (<u>C</u>)
- The process occuring can be called as <em>Combustion</em>. In this process, organic matter is burned in the presence of oxygen (oxidizer). It releases energy and carbon dioxide because carbon in organic matter is oxidized to form CO2.
<em>Which arrow or arrows indicate a process that cycles carbon from living or nonliving organisms? Describe the process or processes you selected.</em>
- from dead organisms to fossils and fossil fuels (E)
- The process explained in the question can be stated as <em>Fossilisation</em>. In this process, dead remains of plants and animals are transformed to fossils under pressure. The organic matter is preserved according to the shape of organism.
<em>Which arrow or arrows represent reactions that demonstrate conservation of mass and energy? Explain your answer.</em>
- from factory emissions to carbon dioxide in atmosphere (C) & from carbon dioxide in atmosphere to photosynthesis (B)
- Two reactions represent the converstion of mass and energy. The burning of fossil fuel (mass) releases energy and carbon dioxide, which is again used by plants to store energy in the process of photosynthesis. This is shown in C and B part of the figure.
Yes it does because it messes up with the circle of all living things and they transfer seeds to places with causes less vegetation in the surrounding area
Answer:
25%
Explanation:
According to this question, a seek stored seeds of a rare and endangered plant. In order to ensure that the seeds remain fresh, 120 seeds are selected to be grown. However, out of these 120 seeds, only 90 germinated. This means that only 90 of 120 seeds are fertile.
This further means that (120-90) = 30 seeds are infertile and hence, could not germinate. In percentage, this can be represented as:
30/120 × 100
= 1/4 × 100
= 100/4
= 25% of the selected seeds are infertile.
Answer:
The importance to goblet cells and other glandular epithelia are to secrete mucus in order to protect the mucous membranes where they are found.
Answer:
haploid cells!
Explanation:
most body cells go through mitosis, which produces a cell exactly identical to the original cell.
what makes meiosis / sexual reproduction unique, is that they use zygotes. the male zygote (sperm) and female zygote (oocyte) go through mitosis TWICE so that they end up with half the number of things they need. When the oocyte and sperm combine during reproduction, the new cell will have a unique HALF from mom and a unique HALF from dad to make a whole unique cell!
